“Bethel…Gilgal…Beer-sheba.” Three centers of pagan worship that had been established by Amos’ time. For Bethel and Gilgal, see commentary on Amos 4:4. Beer-sheba too had become a center of pagan worship (Amos 8:14). God is warning, as He does over and over, about the dangers of pagan worship. Yahweh alone is God and to worship anything but Him will only result in disaster.
